Big Screen

I would like a larger screen than the 13" iPad I currently have mounted on the wall (I use a Homey Pro). There are 24" and larger touchscreens available, but how would I connect my Homey Pro to one perhaps via an Android box? Naturally, I want a dashboard view. Or would I have to switch to a Homey Self Hosted Server? If so, I’d have to re-add all my devices and I currently have over 100 of them.
